Conformable pliable produce storage insert

ABSTRACT

The invention is a conformable pliable storage insert device configured for placement within a basket, and corresponding storage system and method of storing and transporting. The insert device comprises an overall planar and circular configuration defining a planar circular central base having a circumscribing arcuate edge in continuity thereby defining the circular central base, and a plurality of separate planar extensions radially extending distally relative to the base in adjacent circumscribing series, each of the extensions having a pair of arcuate side edges, a proximal edge and a distal edge. The extensions are independently attached to a corresponding arcuate edge portion of the base, and the proximal edge of each planar extension is flexibly attached to the circular central base edge through a hinge panel such that a portion of each arcuate side edge of the extension is structured to overlap the arcuate side edge of an adjacent extension.

BACKGROUND OF THE INVENTION

The invention relates to a container for holding and storing products.More specifically, the invention relates to a liner for placement withinthe container, the liner to function as an interface between a containersurface and the products stored in the container.

Produce, such as fruits and vegetables, are harvested and handledroutinely from orchards and fields as part of their processing forwholesale and consumer purchase. When storing and transporting produce,such as harvested fruits and vegetables, it is desirable to minimizeharsh impact on the produce surfaces and minimize moisture surroundingthe produce to avoid bruising, enhance freshness, and maintain thepleasant appearance of the produce. This is especially important whenhandling relatively fragile fruits and vegetables such as peaches,pears, strawberries, tomatoes, mushrooms, and the like.

Store-purchased produce usually are transitioning away from commercialhandling and processing techniques used on farms such as crating. Atthis point, the produce are handled on a smaller scale and thus, becomevulnerable to harsh physical impact by retail stores and consumers.Produce that require open ambient conditions to ripen, for example, areoften transported and stored in open baskets and containers. Such opencontainers often have a substantially rigid construction, therebyexposing the produce to harsh surface impact. Furthermore, despite beingperforated, baskets still engage the exterior surface of the producewith a roughened and textured interior surface of the basket, e.g.,weave pattern. Although some air flow among the produce articles in thecontainer is permitted, the produce generally experience damage. Sincetypical container materials, such as baskets, and the like are usuallynon-absorbent, prolonged exposure to undesirable moisture can formulateirreparable mold and rotting.

There is a need in the field of produce harvesting, storage, andtransport for a device and/or technique that can reduce impact andmoisture of produce articles when retained in open containers such asbaskets. There is a further need for an intervening surface bufferintercalated between the interior surface of a substantially rigidcontainer and the contained produce therein which can prolong thefreshness and desirable appearance of the produce over time.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the term “produce” is meant to refer to harvested orcollected organic or fragile articles made by natural processes,including but not limited to, fruits, vegetables, eggs, and cut flowers.The term “produce article” is meant to refer to an item of produce, and“produce articles” is meant to refer to the same in plural.

As used herein, the term “basket” is meant to define a rigid orsemi-rigid partially perforated or fenestrated receptacle open at theupper portion wherein the diameter or circumference of the edge of theupper portion is greater than the diameter or circumference of theremaining portions toward the lower base and having an overall cup,hemispheric, or bowl configuration. The circumference of the upperportion, base, or both, can be circular, oval, or elliptical. The rigidor semi-rigid basket material can be composed of various materials.Suitable rigid or semi-rigid natural materials include, but are notlimited to, wood, grass, straw, cardboard, cellulosic compositions, andthe like. Suitable rigid or semi-rigid metallic materials can becomposed of metals and metallic alloys, including but not limited to,aluminum, stainless steel, copper, and the like. Suitable rigid orsemi-rigid plastic and resin materials, glass, and ceramic compositionscan also be used as the basket material. Perforations or fenestrationswhich permit ingress and egress of fluid flow through the basket wallcan be formed as a result of gaps through woven structures, latticestructures, discrete apertures, and the like. The term is meant toencompass woven and non-woven baskets, colanders, sieves, cages, and thelike, which permit some degree of air flow across the wall of thecontainer.

The phrase “configured for placement within a basket” when used to referto the insert device of the invention, is meant to indicate that theoverall size, shape, and dimensions (e.g., height, width, length,diameter, circumference, perimeter) of the insert device generallyconform to the interior surface dimensions and configuration of a basketwithin which the device is to be placed.

The term “circular” when used within the context of the configuration ofthe central base of the device of the invention is not intended to belimited to a perfect circle having a consistent radius at all pointsfrom a central point within the circle to all points along thecircumference. The term “circular” is meant to include oval andelliptical configurations, for example.

The term “planar” as used herein to define the circular central base andextensions of the device of the invention is meant to refer to asubstantially flattened pillow configuration and is meant to includevariations in the thickness of the base and extensions as would betypically associated with the presence of an internal filling materialbetween opposing fabric panels. The term is not meant to refer to aperfectly flat configuration of consistent thickness.

The terms “proximal” and “distal” and inflections thereof when used todescribe a relationship of components to one another within the contextof the invention, unless otherwise specified in relation to a particularcomponent, are referred to relative to the center point of the planarcircular central base. For instance, an object extending radially anddistally from the planar circular central base would be located in anoutward linear direction along an outer circumference relative to apoint and circumference positioned inward, closer toward the center ofthe planar circular central base.

The invention provides a conformable pliable produce storage insertdevice configured for placement within a basket. Referring now to FIG.1, in one embodiment, the insert device (10) comprises an overall planarand circular configuration defining a planar circular central base (11)having a circumscribing arcuate edge (12) in continuity thereby definingthe circular central base. Radiating from the planar circular centralbase (10) are a plurality of separate planar extensions (20), radiallyextending distally relative to the planar circular central base (11) inadjacent circumscribing series thereto. Each of the planar extensions(20) has a pair of oppositely disposed arcuate sides (21) and (22), aproximal edge (23) and distal edge (29). Each one of the planarextensions (20) is independently attached to a corresponding arcuateedge portion (12) of the planar circular central base (11). The arcuateedge portions (12) have intermittently attached planar extensions (20)at varying locations along the circumscribing arcuate edge (12) of thecircular central base (10).

The number of planar extensions (20) can vary. Preferably, the number ofplanar extensions (20) can range from five to seven and aresubstantially evenly distributed along the circumscribing edge of theplanar circular central base (11). The functional and operationalbenefits afforded by the structure of the insert device can be achievedby as few as five planar extensions (20). The number of planarextensions (20) used in the device can increase in order to achieve thecontinuous overlapping functionality of the planar extensions asnecessary according to the dimensions and configuration of the planarextension (20). For instance, in the case with narrower planar extensionshapes, e.g., where the length of the planar extension extends distallyand radially away from the central base panel and this length is greaterthan the width of the planar extension, the number of planar extensionscan range from between about eight to about twelve. Examples of planarextension configurations and shapes where this would be the caseinclude, but are not limited to, shields, petals, chevrons ortongue-shaped planar extension shapes.

One of the advantages afforded by the invention is that, by virtue ofthe structural configuration and overlapping functionality of the planarextensions, the sequential overlapping arrangement of the planarextensions (20) collectively in series form a contiguous circumscribingperimeter surrounding the interior sidewall of the basket adjacent tothe upper edge of the basket opening. Additionally, this arrangement canconform to varying structural configurations and sizes of the basketwithin which it can be inserted.

As seen in FIGS. 1, 4, and 5, for example, the length of the proximaledge (23) of the planar extension (20) is generally parallel to thecorresponding edge portion (12) of the circular central base (11) towhich it is attached. The proximal edge (23) of each planar extension(20) is flexibly attached to a corresponding edge portion (12) of theplanar circular central base (11) through a flexible hinge panel (30) asshown in FIG. 3. The flexible hinge panel (30) permits free movementalong a general latitudinal running axis β along the width of theflexible hinge panel (30) so as to permit free rotational motionthereabout (shown as axis α) between the planar extension (20) relativeto the planar circular central base (11).

Referring now to FIG. 4, preferably the proximal edge (23) of eachplanar extension (20) runs generally parallel to the correspondingarcuate edge portion (12) of the circular central base (11) to which itis attached. By virtue of the collective construction and dimensions ofthe insert device (10) of the invention, at least a portion of each ofthe arcuate side edges, (21) and (22), of the planar extension (20), isstructured to overlap and extend beyond the side edge (21) of anadjacent planar extension (20) in series, as shown in FIG. 5, andcollectively illustrated in FIG. 1, for example. As assembled, theflexible hinge panels (30) are mechanically discrete relative toadjacent planar extensions (20), in that the planar extensions (20) arenot attached other than through flexible hinge panel (30) to the arcuateedge portion (12) of the planar circular central base (11). The hingedextensions (20) detachably interact in sequence to permit a continuousoverlapping arrangement with adjacent planar extensions (20) surroundingthe entire perimeter or circumference of the planar circular centralbase (11). In a preferred embodiment and as seen in the figures, thearcuate edge portion (12), overlapping planar extensions (20) and theflexible hinge panels (30) collectively form a space between each of theflexible hinge panels (30) so as to permit ingress and egress of airflow there through.

The configuration or shape of the planar extensions (20) can vary,provided the proximal edge (23) and first and second arcuate side edges(21) and (22), respectively, adjacent to the attachment site of theflexible hinge panel (30) are present and the shape and the functionalsequential overlapping position between planar extensions (20) asdescribed is maintained. In the Figures, the planar extension(s) (20)are depicted as a generally elongated elliptical shape with arcuate sideedges rounded to resemble a “capsule.” Additional planar extensionshapes that can be used include, but are not limited to, circles, ovals,rounded rectangles, rounded squares, shields, petals, chevrons ortongue-shaped planar extension shapes, and the like. Although depictedin the figures as being the same, alternating, or otherwise differingplanar extension shapes can be used, provided the desired positionalsequential overlapping occurs along the entire perimeter of the planarcircular central base (11).

Referring now to FIG. 4, a preferred embodiment of the insert device ofthe invention (partial view) is depicted wherein the planar extension(20) comprises a structure whereby the length L1 of the planar extensionbetween the oppositely disposed arcuate edges (21) and (22) is greaterthan the length L2 of the planar extension (20) between the proximaledge (23) and the distal edge (29) of the planar extension (20). LengthL1 can vary relative to length L2, the total number of flexible planarextensions (20), and overall configuration of the insert device (10) inorder to achieve the desired resultant overlapping arrangement of theflexible panel extensions (20) over one another along the outercircumference of the insert device (10) as described herein. In general,the ratio of length L2 to length L1 can range from between 1:1 to about7:1. Although depicted as a “capsule” shape formed from a pair ofoppositely disposed arcuate side edges (21) and (22) and straightproximal edge (23) and straight distal edge (29), all edges of theflexible panel extension (20) can be arcuate or curvilinear, and one orboth of the proximal edge (23) and distal edge (29) can be arced inwardtoward the center of the panel extension (20) or arced outward.

Referring to FIG. 3 and FIG. 6, the planar circular central base (11) ofthe insert device (10) of the invention comprises a pair of first andsecond oppositely disposed fabric panels, (41) and (42), respectively,having a layer of pliable filling material (50) between and containedtherein. The oppositely disposed fabric panels (41) and (42) arecontinuously attached to one another along the entire length of theirrespective perimeters. Likewise, each of the separate planar extensions(20) comprises a pair of first and second oppositely disposed fabricpanels, (61) and (62), respectively, having a layer of pliable fillingmaterial (70) between and contained therein. The oppositely disposedfabric panels (61) and (62) are continuously attached to one anotheralong the entire length of their respective perimeters.

The thickness (T1) of the planar circular central base (11) andthickness (T2) of the planar extensions (20) (see FIG. 3, for example)can be varied in accordance with the invention. The thickness andpliable properties of these components and overall insert device (10) ofthe invention can be adjusted as part of the manufacturing process byincreasing or decreasing the amount of pliable filler material used. Itis important when varying thickness, however, that the overallconfiguration of the device maintains a substantially planarconfiguration and it does not part from the functionality of theinvention.

In a preferred embodiment, and as shown in FIGS. 1, 2, 5, and 6, thefirst and second oppositely disposed fabric panels (41) and (42) of theplanar circular central base (11) and the first and second oppositelydisposed fabric panels (61) and (62) of each of the planar extensions(20) can be fixed through the interior along a transverse axis γ (seeFIG. 6) through panel attachments. In one embodiment and as shown in theFigures, the planar circular central base panel attachment (81) andplanar extension panel attachment (82) are positioned in the approximatecentral area of the component panels and configured as discreteattachments. The panel attachments (81) and (82) function to inhibit theinterior migration of the filling material and maintain more uniformdistribution of the filling material within. The panel attachments (81)and (82) can be formed using a threaded sewn stitch (as illustrated),stud, rivet, adhered to, or otherwise fastened to fixedly secure theopposing panel. The panel attachments (81) and (82) can perforate thefilling material or directly attach the interior of each opposing panel.

Various panel attachment techniques and structures can be employed. Acombination of two embodiments of panel attachments are illustrated inthe Figures. Referring now to FIG. 1, a cross-shaped centrally locatedstitch as panel attachment (81) can be located in the center of theplanar circular central base (11) component, and a linear stitch panelattachment (82) can be located in the central area of each planarextension (20). In an alternative embodiment, various configurations toattach the fabric panels can be used, including but not limited to,multiple discrete attachments, contiguous quilt stitching, and the like.Preferably, single discrete centrally located fabric attachments areused with the invention so as to optimize the pliability propertiesafforded by the internal filling material.

The arcuate edge portions (12) of the planar circular central base (11)and the proximal edge (23) of the planar extensions (20) are attached toone another indirectly through a flexible hinge panel (30).Specifically, the flexible hinge panels (30) function to permit easymotion of the individual planar extensions (20) relative to the planarcircular central base (11) in order to facilitate ready conformation ofthe insert device (10) into a basket (90) (as illustrated in FIG. 2, forexample). The flexible hinge panel (30) is preferably a simpleconstruction from a single or double layer of flexible material withoutthe presence of filling material therein. The width and length of theflexible hinge panel (30), and the resulting connective distance betweenthe arcuate edge portion (12) of the planar circular central base (11)and the planar extension (20) can vary, provided the desired sequentialoverlapping arrangement of the first and second oppositely disposedarcuate edges (21) and (22) of the planar extensions (20) do not partfrom the functionality and operation of the invention. Preferably, thehinged distance between the edge portion (12) of the planar circularcentral base (11) and proximal edge (23) of the corresponding planarextension (20) is relatively minimal so as not to create substantialgaps between the insert device (10) and the interior surface of thebasket (90).

In addition to the thicknesses (T1) and (T2) of the insert device (10)components, the overall dimensions of the insert device (10) can bevaried according to the contemplated or desired basket (90) within whichit is to be placed. Insert device (10) dimensions such as overalldiameter, planar extensions (20), planar circular central base panel(11) diameter, planar extension (20) length and width, and the like—canall be modified as part of the manufacturing process in this manner.Furthermore, although the insert device (10) of the invention isdescribed and depicted as having an overall substantially symmetricalconstruction and configuration, the insert device can be constructed asan asymmetrical configuration as well provided the functional andoperational benefits and advantages associated with the invention arenot substantially attenuated or compromised. For example, the circularcentral base panel (11) and overall configuration of the insert devicecan be oval or elliptical to conform to an oval or an elliptical shapebasket.

The overall dimensions of the insert device (10) of the invention can bedetermined according to the dimensions and shape of the intended basket(90) into which it may be received, and the insert device (10) can bemanufactured accordingly. For instance, the general diameter of theplanar circular central base (11) would correspond to the centralreceiving portion of the basket (90), (see FIG. 2, for example), i.e.,the diameter of the basket interior bottom. An important functionalaspect of the invention is that the insert device (10) is structured toreadily and substantially adapt and conform to the interior dimensionsof the basket (90). The insert device (10) of the invention can readilychange from a flattened, horizontal state (see FIG. 1, for example) intoa conforming variable hemispheric or “bowl-like” state (as shown in FIG.2, for example). Another important functional aspect of the invention isthat during and at the conforming state, the paneled components of theinsert device ((41) and (42) of the planar circular central base (11),and (61), and (62) of planar extension (20)), aside from the flexiblehinge panel (30), are absent resulting and undesirable crimping,pleating, or folding of their interior and exterior surfaces as mightoccur with a traditional single contiguous fabric panel basket linerstructure.

Materials:

First and second oppositely disposed fabric panels, (41) and (42)respectively, of the planar circular central base (11), first and secondopposing fabric panels, (61) and (62) respectively, of the planarextension (20), and the flexible hinge panel (30), can be composed offlexible woven or non-woven fabric material. Suitable fabric materialthat can be used for these components of the insert device (10)preferably include, but are not limited to, fabrics that are flexible,breathable or porous, wick moisture, soft, washable, and reusable.Suitable fabrics include, but are not limited to, natural woven cotton,bamboo, cotton-synthetic blends such as 80% cotton 20% polyester, andthe like. Different components of the insert device (10) can be composedof the same or different fabrics having different properties.

Suitable filling materials that can be used in the planar circularcentral base (11) and planar extensions (20) of the insert device (10)include, but are not limited to, pliable natural and synthetic materialsthat permit some degree of air movement and circulation. Suitablepliable natural materials can include non-woven cotton, cotton, bamboo,sponge, and excelsior. Suitable synthetic filling materials include, butis not limited to, polyester fiberfill, such as POLY-FIL® polyesterfiberfill (available from Fairfield Processing Corporation, Danbury,Conn.); and polyurethane foam materials, such as POLY FOAM™ (availablefrom American Excelsior Company, Arlington, Tex.). In one embodiment, apreferred filling material for ideal functionality is polyurethane foam.In a further embodiment, different filling materials may be used indifferent components of the insert device. It is an important aspect ofthe invention that whichever filling material is selected, that itpossess a pliable, soft, cushion and breathable property in order tofully realize the benefits afforded by the invention.

How to Make

The insert device (10) of the invention can be made using conventionaland readily available materials, techniques, and equipment to those inthe textile manufacturing and construction fields, such as sewingmachinery. In one example, and referring now to FIG. 6, the first andsecond oppositely disposed fabric panels (41) and (42) of the planarcircular central base (11), with a layer of filling material (50)positioned between, can be attached along the entire length of theperimeter formed by the contiguous circumscribing edge portions (12).Similarly, each of the first and second oppositely disposed fabricpanels (61) and (62) of the planar extensions (20) can be attached alongthe perimeter including first and second oppositely disposed arcuateedges (21), (22) and proximal edge (23), so as to contain a layer offilling material (70) within. The proximal end (31) (see FIGS. 3, 4, 5and 6, for example) of the flexible hinge panel (30) can be integrallysecured to the edge portions (12) of the planar circular central base(11), and the distal end (32) of the flexible hinge panel (30) can beintegrally secured to the proximal edge (23) of each planar extension(20). The securing of the flexible hinge panel (30) can be accomplishedeither as part of the attachments of the first and second oppositelydisposed fabric panels of each of the planar circular central base (11)and planar extensions (12), or alternatively, secured following theattachment of the perimeters of the first and second oppositely disposedfabric panels. The attachment of the flexible hinge panel (30) andplanar extensions (20) to the planar circular central base (11) arerepeated for each flexible hinge panel (30) and planar extensions (20)pairing to be constructed for the insert device (10). The layers offilling material (50) and (70) can be secured into position upon finalassembly by applying threaded stitching through the central area of theassembled fabric panels of the planar circular central base (11) andplanar extensions (20) along transverse axis γ (see FIG. 6).

Attachments of the planar extensions (20) to the planar circular centralbase (11) may be accomplished using conventional fabric attachingmaterials and techniques, including but not limited to, stitching usingthread, adhesive, riveting, and the like. The fabric panels may beattached continuously and circumscribing along the entire length of theperimeters of each planar extension (20) and planar circular centralbase (11). Preferably, whichever technique is employed, the flexibilityalong the seams should not be substantially compromised or attenuated.Accordingly, in one embodiment, threaded stitching is most preferred.

How to Use

The invention may include a produce, method, and system for storing andtransporting produce comprising a basket, and a conformable producestorage insert device configured for placement within the basket.According to one method for storing and transporting produce, a basketand a conformable pliable produce storage insert device can be assembledsuch that the insert device is initially placed inside a basket, atleast one produce article may be received by a conformable pliableproduce storage insert device, with the insert device conformablypositioned within the interior surface of a basket. Referring to FIG. 2,the insert device (10) of the invention can be inserted into a basket(90) and conforms to the interior configuration of the basket (90) suchthat the exterior surfaces of the insert device (10) contact theinterior surface of the basket (90). Produce articles, such as fruit andvegetables (not shown), can then be placed into the exposed open surfaceof the insert device (10). The collective structural features andconfiguration of the insert device (10) can permit some degree of airmovement and circulation surrounding the produce articles, and provide asoft pliable moisture absorbent contacting surface within the basket tosustain freshness of the produce items. Accordingly, the inventionmitigates irreparable mold, rotting, spoilage, and bruising of produceitems and enhances storage longevity.

In an additional embodiment of the invention as depicted in FIG. 7, thepreservation characteristics associated with the insert device (10) ofthe invention can be further enhanced by a planar extension (20) furthercomprising a pouch (99) structured and dimensioned to receive a thermalpack (100) therein. The phrase “structured and dimensioned to receive athermal pack therein” is meant to define the construction of a pouchhaving interior dimension, (e.g., height, width, depth) that correspondsto a thermal pack, selected and constructed having exterior dimensions(e.g., height, width, depth), so as to be received within the planarextension pouch. See FIG. 7, for example. The pouch (99) can be locatedon either the interior surface or the exterior surface (as shown) of theplanar extension (20). Suitable pouches can be constructed as a simpleopen pocket (as shown), or alternatively, can be structured as acloseable pocket, buttoned pocket, snap pocket, Velcro® (available fromVelcro USA, Inc., Manchester, N.H.) reversibly sealable pocket, zipperedpocket, overlapping folds of fabric, and the like. Pouches can bepresent on few planar extensions, all of the planar extensions, oralternating planar extensions of the insert device (10).

In yet another embodiment of the invention as depicted in FIG. 8, thecircular central base (11) component (shown by itself in separatedstate) of the insert device of the invention can further comprise apouch (199) on the bottom surface fabric panel (42) wherein the pouch(199) is structured and dimensioned to receive a thermal pack (200)therein. Similarly as with the planar extension pouch described hereinabove, The phrase “structured and dimensioned to receive a thermal packtherein” is meant to define the construction of a pouch having interiordimension, (e.g., height, width, depth) that corresponds to a thermalpack, selected and constructed having exterior dimensions (e.g., height,width, depth), so as to be received within the circular central basepouch (199). Although the thermal pack (200) for the circular centralbase (11) is depicted as having a circular configuration, a variety ofshapes are possible e.g., a corresponding circular configuration to thespecific circular central base (11) into which the thermal pack (200)can be placed.

For purposes of accessibility and convenience, the pouch (199) ispreferably located on the bottom of the circular central base (11). Itis possible, nevertheless, for the upper interior surface of thecircular central base s11) to comprise a pouch structure. Again as withthe planar extension pouch embodiment, suitable pouches can beconstructed as a simple open pocket (as shown), or alternatively, can bestructured as a closeable pocket, buttoned pocket, snap pocket, Velcro®reversibly sealable pocket, zippered pocket, overlapping folds of fabric(as illustrated in FIG. 8), and the like.

Various combinations of the embodiments comprising the thermal pack canbe used in the invention. For instance, the planar extension(s) alone,the circular central base alone, or a combination of both planarextension(s) and circular central base can comprise one or more thermalpacks therein. Furthermore, combinations of different pouch structuresand configurations can be employed within a single insert device of theinvention. Preferred pouch structure(s) for the planar extension pouchembodiment, circular central base pouch embodiment, or both, can be apouch wherein the opening through which the thermal pack can be insertedthrough is formed as an overlapping fold of two portions of the fabricpanel. One example of this overlapping fold pouch structure isillustrated in FIG. 8, whereby the thermal pack can be inserted underthe outer fold (195) and subsequently tucked under the inner fold (196)to secure the thermal pack (200) within the circular central base (11)of the insert device. A similar pouch structure as described can also beused for the planar extension thermal pack embodiment.

Suitable thermal packs in either of these described embodiments that maybe used, but is not limited to, include thermal freezer packs, readilyavailable reusable sealed plastic bags, containers containing afreezable liquid or gel for freezing or refrigeration, re-fillable orre-sealable ice bags, as well as single-use endothermic reactivechemical compositions. A variety of suitable thermal cold packs whichare readily available to those in the art can be employed in combinationwith the invention. Suitable thermal cold packs that can be used in theinvention include, but is not limited to, cold packs that contain aninsulating material which, upon cooling in a refrigerator or freezer,gradually warm back to ambient temperature, cold packs that operate viaa change of phase of the components of the cold pack, and cold packsthat employ chemical components that dissolve endothermically in asolvent.

Examples of thermal cold packs that employ an insulating material arecold packs that contain a coolable or freezable liquid, e.g., water, ora gel. In one embodiment, these cold packs are cooled in a refrigeratoror freezer. Typical gels are based on the gelation of xanthan gum,locust bean gum, gum tragacanth, guar gum, hydroxypropylmethylcellulose, absorbent polymers, and the like. Gels may also bebased on a high molecular weight polyacrylic acid cross-linked with apolyalkenyl ether, also referred to as a cis-carbomer.

Thermal cold packs using phase change materials may be converted betweensolid and liquid phases and utilize their latent heat of fusion to coolduring such phase conversion. The latent heat of fusion is greater thanthe sensible heat capacities of the materials. Accordingly, the amountof energy absorbed upon melting or released upon freezing is greaterthan the amount of energy absorbed or released upon increasing ordecreasing the temperature of the material by 10 degrees C. In oneembodiment, water is used as a phase changing material.

Endothermic dissolution cold packs contain certain chemical compoundsthat, once dissolved into a solution, result in a lowering of thetemperature of the solution below ambient temperature. On dissolution,these compounds take up heat from the surrounding environment. Forexample, inorganic salts or soluble organic compounds known to have apositive (greater than zero) enthalpy of aqueous solution are used tomake the reduced temperature solutions useful in cold packs.

Various conventional techniques can be used toapply designs, patterns, or colors to flexible fabrics, including butnot limited to, stenciling, screen printing, dying, weaving, stitching,appliqués, and the like.

Although the full benefits and advantages afforded by the invention aremanifested in the storage and handling of produce articles, additionaluses are contemplated by the invention as well and its use is notlimited to produce articles such as fruits and vegetables. For instance,baked bread items, such as rolls and doughnuts, can also be used in theinvention.
